That's kind of a trick question. Specific heat - also known as "heat capacity" is the energy required to change the temperature by a fixed amount. In the case of an isothermal process, the temperature isn't changing.
Since specific heat is defined as (δH/δT), isothermal heat capacity would be (δH/δT)T which means, in English, the change in enthalpy with a change in temperature when the temperature isn't changing... you see the problem. If δT = 0, then δH/δT = ±∞ (positive if heat is added to the system to keep the temperature constant, negative if heat was removed to keep it isothermal)
You could write some equations such that the heat capacity becomes a term in the equation. What you will generally find though is that the heat capacity is multiplying a dT term and when dT is zero, that term drops out and heat capacity is irrelevant for the calculation.

Why carnot cycle is called a two adiabatic and two isothermal process?
Adiabatic means there's no heat transference during the process; Isothermal means the process occurs at constant temperature. The compression and expansion processes are adiabatic, whereas the heat transfer from the hot reservoir and to the cold reservoir are isothermal. Those are the two adiabatic and isothermal processes.
What is energy is transferred to a gas as heat and work If there is no change in its internal energy the process is known as?
The process is known as an isothermal process. In an isothermal process, the energy transferred to the gas as heat and work results in no change in the gas's internal energy because the temperature remains constant throughout the process.
How does the volume change in an isentropic process?
The entropy of an ideal gas during an isothermal process may change because normally the entropy is a net zero. The change of on isothermal process can produce positive energy.

Is isothermal expansion reversible under ideal conditions?
No. All processes involving heat transfer are not reversible, since they result in an increase in entropy. Isothermal expansion implies heat transfer to maintain the system at a constant temperature. Normally an expanding gas would cool if there were no heat entering the system. Adiabatic processes involve no heat transfer and are reversible. The temperature can (and usually does) change during an adiabatic process.
Which of the following is true of an isothermal process Temperature is constant W equals Q ΔU equals 0 Pressure is constant?
Temperature is constant during an isothermal process. The work done (W) is equal to the heat added (Q). The change in internal energy (ΔU) is zero for an isothermal process. The pressure can vary during an isothermal process, depending on the specific conditions.
What is the relationship between enthalpy and the isothermal expansion process?
In an isothermal expansion process, the enthalpy remains constant. This means that the heat energy exchanged during the expansion is equal to the work done by the system.
What isothermal process?
Isothermal process is a process in which change in pressure and volume takes place at a constant temperature.
What is true about isothermal process?
An isothermal process is one which does not take in or give off heat; it is perfectly insulated. Iso = same, thermal = heat. In real life there are very few isothermal processes. Heat loss accounts for most process inefficiencies.
What are the key differences between an adiabatic and isothermal graph in thermodynamics?
In thermodynamics, the key difference between an adiabatic and isothermal graph is how heat is transferred. In an adiabatic process, there is no heat exchange with the surroundings, while in an isothermal process, the temperature remains constant throughout the process.
Why carnot cycle is called a two adiabatic and two isothermal process?
Adiabatic means there's no heat transference during the process; Isothermal means the process occurs at constant temperature. The compression and expansion processes are adiabatic, whereas the heat transfer from the hot reservoir and to the cold reservoir are isothermal. Those are the two adiabatic and isothermal processes.

What is different between adiabatic system and isothermal system?
An isothremal process is one in which the temperature is constant. heat can be gained or lost in order to maintain a constant tempereature. An adiabatic process is one in which there is no heat exchange between a system and its surroundings. It does not matter whether the temperature of the system is constant or not.
What statement best describe the isothermal process?
An isothermal process is one where the temperature remains constant throughout. This means that the internal energy of the system stays the same, as the heat transfer into the system is balanced by the work done by the system. In an ideal gas, this results in no change in the pressure or volume during an isothermal process.
What are examples of isothermal process?
An isothermal process is a change in a system where the temperature stays constant (delta T =0). A practical example of this is some heat engines which work on the basis of the carnot cycle. The carnot cycle works on the basis of isothermal.
